Answer:
40.53 kg
Explanation:
Juggles 's mass = Mj
Bangles 's mass = 70 kg
Potential Energy is the Energy that an object gets due to its height of location
<em>Potential Energy = mass * gravitational acceleration * height</em>
Juggeles' s Potential Energy = Bangles potential energy
Mj * g * 3.8 = 70 * g * 2.2
Mj = 40.53 kg
Answer:
The force of the floor on the briefcase
Explanation:
The briefcase hits the floor and stops the falling which is reacting to the briefcase that was falling and hits the floor.
The falling briefcase would be the action force because it is moving downward
and
The reaction force would be the floor because it will react on the briefcase.

The acceleration on surface of moon =1.67m/s^2
Weight =mass ×acceleration
=7×1.67
=11.69N
The whole secret of things that are balanced on a pivot like this is:
The sum of all of the 'moments' is equal on both sides.
The moment of each weight is (the weight) times (its distance from the pivot).
If you add up those for each eight on one side, it has to be equal to the sum
of all the ones on the other side.
<u>2. a).</u>
The moments on the right side are: (4 x 0.15) and (1 x 0.40).
They add up to (0.60 + 0.40) = 1.00
The only moment on the left side is (C x 0.25). Both sides have to be equal.
C x 0.25 = 1.00
Divide each side by 0.25, and you have C = 4 N .
===========================================
<u>2. b).</u>
The only moment on the left side is (5 x 0.40) = 2.00
The moments on the right side are (1 x 0.20) and (D x 0.30)
They add up to (0.3D + 0.2).
Both sides have to be equal. 0.3D + 0.2 = 2.0
Subtract 0.2 from each side: 0.3D = 1.8
Divide each side by 0.3: D = 6 N
Answer:
The resulting static friction force acting on the crate is 10 N.
Explanation:
Given that,
Coefficient of static friction = 0.50
Normal force = 20 N
We need to calculate the resulting static friction force acting on the crate
Using formula of static friction force
Where, N = normal force
= Coefficient of static friction
Put the value into the formula
Hence, The resulting static friction force acting on the crate is 10 N.
